Modeling hydraulic resistance of floodplain vegetation

Abstract

Thesis gives an overview of theory of turbulent flows, in particular related to wall-bounded flows and applicability in river engineering; focusses on the vegetation resistance method pro- posed; an alterna- tive description of depth-averaged flow over (idealized) vegetation is pre- sented; the method is compared to flow measurements that were collected in natural waterways; a synthesis of investigated vegetation resistance models is given, and detailed characteristics of the two methods are compared; consequences for river flood forecasting and opportunities for other fields of applications are discussed; supplemented with recommendations for practical application and future research.
